Error resolved by changing the code of GeoCity and GeoCountry to: ` @Bean(name="GeoIPCity") public DatabaseReader databaseReader() throws IOException{ Resource resource = new ClassPathResource("maxmind/GeoLite2-City.mmdb"); InputStream databaseStream = resource.getInputStream(); return new DatabaseReader.Builder(databaseStream).build();

}`

@Bean(name = "GeoIPCountry") public DatabaseReader databaseReader() throws IOException, GeoIp2Exception { Resource resource = new ClassPathResource("maxmind/GeoLite2-City.mmdb"); InputStream databaseStream = resource.getInputStream(); return new DatabaseReader.Builder(databaseStream).build(); }

Hey, @rayacode.

Please include a link to the article you're referring to so we can look into this.

there is no article, i tested on actual debian 12 local vps, by using apache2 as proxy server, and spring boot app(tomcat) of this project behind the apache2 server. there are some changes of mine to the project to fit to what i want, but not related to the issue. seems like there an issue with the Spring ResourceUtils.getFile() methd, It is trying to access maxmind/GeoLite2-Country.mmdb but it is unable to find it, in modified method, "new ClassPathResource("maxmind/GeoLite2-City.mmdb")" creats resource that represents the maxmind/GeoLite2-City.mmdb file in the classpath, resource.getInputStream() then gets an InputStream that reads from the file the DatabaseReader.Builder constructor is changed to accept an InputStream instead of a File, allowig it to read from the maxmind/GeoLite2-City.mmdb file even when it is inside jar file

We're considering this article: https://www.baeldung.com/spring-security-restrict-authentication-by-geography

This issue will remain open until we look into this.

oh i see what you mean by article, i actually didn't read those completely, this repo is nice code template for the security of the web apps, i found it this way not by learning with articles... .
